The inventionwill be best understood by A steam blow-off valve 31' isconnected in a reference to the accompanying drawings communicationwith'the compartment 1 8. which form a part of this specification, andabove the normal water level by the pipe 32. in which, A'by-pass 33connects the pipe 32 with the air Fig. 1 is a side elevational view ofthe ininlet pipe 12 so as to humidify the air which vention. isdelivered intoitheinteriorof the" shell 11.

It isanobject of the present invention to provide an apparatus of thisclass in which a force circulation of airflwould be effected Fig. 3 is asectional View taken on line as of Fig-2.

Fig. 4 is a fragmentary sectional view of the invention illustrating thehumidifier.

In the device I provide supporting legs 9 which serve to support thesuperstructure f comprising an outer shell or housing 10. en-

In operat on, the gasburner serves to heat the Water which circulates through the comof thewater and partment 18 and this water willheat the surface with. whichthe air will be brought into contact. Pipes 36 travel the interior ofthe shell 11 and the air brought into theinterion I of the shell 11will-pass upwardly and contact with these pipes 36.; Similarly, that portion of the air which passes through the conduits- 15 will contact withthe pipes 24 and thus the air will become heated. The portion of the;air passing through the tubes or conduits 15 will pass upwardly in thepassages 35 and thus inducing a draft from the bottom of the passagesdrawing more air upwardly into the hood or cover fine 88 and to whichsuitable piping may be connectedto conduct the hot airto any de-,

sired location. 7

37, fromwhich leads the i 39 supported by the brackets 40 may be used' cas an auxiliary heater.

It is obvious that a simple and compact structure is provided whereby ahot air heats ing system is established with the use of hot water as theheating agent.

When desired, an electric heating element While I have illustrated anddescribed the preferred form of construction of my invention, I do notwish to limit myself to the precise details of structure shown, butdesire to avail myself of such variations and modifications as may comewithin the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is: V V

1. A heater of the class described, comprising: an inner shell; an outershell spaced from and enclosing said inner shell; a plurality of tubestraversing said inner shell and communicating at opposite ends with thespace between said inner shell and said outer shell; conduits extendingthrough the space 7 between said inner shell and said outer shell andcommunicating with the interior of said inner shell and the exterior ofsaid outer shell; a plurality of pipes communicating with the spacebetween said inner shell and said outer shell and traversing saidconduits; and means for delivering air into the interior of said innershell.

2. A heater of the class described, comprising: an inner shell; an outershell spaced from the enclosing said inner shell; a plurality of tubestraversing said inner shell and communicating at opposite ends with thespace between said inner shell and said outer shell; conduits extendingthrough the space between said inner shell and said outer shell andcommunicating with the interior of said inner shell and the exterior ofsaid outer shell; a plurality of pipes communicating with the spacebetween said inner shell and said outer shelland traversing saidconduits; means for delivering air into the interior of said innershell; means for delivering hot water into the space between saidshells; a cover for said outer shell and providing there- 'with aplurality of vertically extended passages; and a hood covering saidshells and said passages.

In testimony whereof I have signed the 5 foregoing specification.

MARLIN WARREN.
